[Zope] WHY ? -- Performace in serving large media files from ZODB vs from external file system

Hi Zopers

In the performance for large image files discussion Dieter Wrote

What could be the reason for being "slow". Since the files are large, =
the setup time can be ignored ( time to locate the object) Once the =
object is found only thing that remains is the reading the file from DB =
( should be a plain read) and push it to the connection. I do not see a =
reason for beeing slow on the db read once the data is located inside =
the DB.=20
Data may or may not be in a continuous block as in the file system. I =
see no code / decode or copmress/decompress in the process. So why =
should the ZServer be slow? Do I miss something here?
IMHO moving some stuff from zope for minimal performance reasons breaks =
zope OOWEB idea!

Both will be quite slow when servered by ZServer.
With LocalFS, you can them serve however with a standard
WWW server, e.g. Apache.
